Detailed Description

The LaserProxy class is used to control a laser device.

The latest scan data is held in two arrays: ranges and intensity. The laser scan range, resolution and so on can be configured using the Configure() method.


Member Function Documentation

void PlayerCc::LaserProxy::Configure ( double  aMinAngle,
double  aMaxAngle,
uint32_t  aScanRes,
uint32_t  aRangeRes,
bool  aIntensity,
double  aScanningFrequency 
)

Configure the laser scan pattern.

Angles min_angle and max_angle are measured in radians. scan_res is measured in units of 0.01 degrees; valid values are: 25 (0.25 deg), 50 (0.5 deg) and 100 (1 deg). range_res is measured in mm; valid values are: 1, 10, 100. Set intensity to true to enable intensity measurements, or false to disable. scanning_frequency is measured in Hz

player_pose3d_t PlayerCc::LaserProxy::GetPose ( ) [inline]

Accessor for the pose of the laser with respect to its parent object (e.g., a robot).

Fill it in by calling RequestGeom.

References player_pose3d::px, player_pose3d::py, and player_pose3d::pyaw.

player_pose3d_t PlayerCc::LaserProxy::GetRobotPose ( ) [inline]

Accessor for the pose of the laser's parent object (e.g., a robot).

Filled in by some (but not all) laser data messages.

References player_pose3d::px, player_pose3d::py, and player_pose3d::pyaw.

double PlayerCc::LaserProxy::MinLeft ( ) const [inline]
Deprecated:
Minimum range reading on the left side
double PlayerCc::LaserProxy::MinRight ( ) const [inline]
Deprecated:
Minimum range reading on the right side
double PlayerCc::LaserProxy::operator[] ( uint32_t  index) const [inline]

Range access operator.

This operator provides an alternate way of access the range data. For example, given an LaserProxy named lp, the following expressions are equivalent: lp.GetRange(0) and lp[0].

void PlayerCc::LaserProxy::RequestConfigure ( )

Request the current laser configuration; it is read into the relevant class attributes.

void PlayerCc::LaserProxy::RequestGeom ( )

Get the laser's geometry; it is read into the relevant class attributes.
